I think this would have been an absolute barn burner and a war. Vargas before the Trinidad fight vs Castaño today at 154.
Feroz destroys that guy. Too good a boxer, too intense, too ferocious. Round 5 vs. Trinidad is one of the greatest rounds ever boxed by a young fighter; he really wasn't more than a matter of an inch here and an inch there from defeating Tito at just age 22. Let that marinate. Even the post-Trinidad versions whoop the Argentine.
I'd back Castano. He's more professional than Vargas, who was slow, easy to hit and didn't have the best gas tank.
